GpsUpdatePipeline(Json json)
Creates pipeline from Json generated from NoFloJs

Properties

connections ↔ List<PipelineConnection>
Connections in pipeline
late, final
end ↔ String
Ending operation process
late, final
hashCode → int
The hash code for this object. [...]
read-only, inherited
hasListeners → bool
read-only, inherited
initialized → bool
Checks whether the controller has already been initialized.
read-only, inherited
isClosed → bool
Checks whether the controller has already been closed.
read-only, inherited
json → Json
Json used to create this pipeline
final
listeners → int
read-only, inherited
name → String
Pipeline name
final
onDelete → InternalFinalCallback<void>
Internal callback that starts the cycle of this controller.
final, inherited
onStart → InternalFinalCallback<void>
Called at the exact moment the widget is allocated in memory. It uses an internal "callable" type, to avoid any @overrides in subclases. This method should be internal and is required to define the lifetime cycle of the subclass.
final, inherited
processes → PipelineProcesses
Map of process name to PipelineOperation name
final
registry ↔ PipelineOperationsRegistry
Operations registry
late, final
result → Rx<PipelineFlowItem?>
Result of pipeline operation
final
runtimeType → Type
A representation of the runtime type of the object.
read-only, inherited
start ↔ String
Starting operation process
late, final

Methods

$configureLifeCycle() → void
inherited
addListener(GetStateUpdate listener) → Disposer
Register a closure to be called when the object notifies its listeners.
inherited
addListenerId(Object? key, GetStateUpdate listener) → Disposer
inherited
dispose() → void
@mustCallSuper, inherited
disposeId(Object id) → void
To dispose an id from future updates(), this ids are registered by GetBuilder() or similar, so is a way to unlink the state change with the Widget from the Controller.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
inherited
notifyChildrens() → void
@protected, inherited
onClose() → void
Called before onDelete method. onClose might be used to dispose resources used by the controller. Like closing events, or streams before the controller is destroyed. Or dispose objects that can potentially create some memory leaks, like TextEditingControllers, AnimationControllers. Might be useful as well to persist some data on disk.
inherited
onInit() → void
Listens to LocationUpdate emitted and processes same
override
onReady() → void
Called 1 frame after onInit(). It is the perfect place to enter navigation events, like snackbar, dialogs, or a new route, or async request.
inherited
processItem(PipelineFlowItem? item) → dynamic
Process PipelineFlowItem along pipeline
refresh() → void
@protected, inherited
refreshGroup(Object id) → void
@protected, inherited
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that the object notifies.
inherited
removeListenerId(Object id, VoidCallback listener) → void
inherited
toString() → String
String representation
override
update([List<Object>? ids, bool condition = true]) → void
Rebuilds GetBuilder each time you call update(); Can take a List of ids, that will only update the matching GetBuilder( id: ), ids can be reused among GetBuilders like group tags. The update will only notify the Widgets, if condition is true.
inherited

Operators

operator ==(Object other) → bool
The equality operator. [...]

Static Methods

parseConnections(Json json, String endProcess) → List<PipelineConnection>
Generates connections from the json data
